SilvX5,

The Treo 700p for now is being released for only Sprint and Verizon. EV-DO is only available on CDMA network which is what Sprint and Verizon uses. There has not been any talk about a GSM version.

There are no SIM cards in CDMA phones.

When you refer to "unlock version", you are referring to GSM phones (e.g. Cingular, T-Mobile, etc.)

GSM also has a hi-speed data network, but apparently not as robust as CDMA's EV-DO (which allows one to surf the internet wirelessly at broadband speed).
